I have two questions. Can these be fitted with no problems to ABS equiped bikes or do you have to specify and how does changing the diameter of the wheel affect the speedo readings?

 I've bought a set of the attitude max wheels off Ian, I've got the 21.5" for the front and the 16.5" for the rear .. As this is the stock size for my 06 heritage, am I going to need wheel spacers at all? Any info will be greatly appreciated guys

Old thread I know but just a heads up if you have abs fitted and change to a 21 inch up front with 120 70 tyre it will throw an abs fault. Have to use a Thundermax Tracmax abs module to correct the signal to the abs controller. Otherwise if you don't want white wall go with a 130 60 tyre and you shouldn't need the module.

Also the wheels don't have to be strictly abs hubs....get any wheel and fit the abs bearing kit, this allows for more choice and style of wheels.
